Operation principle：The present invention is widely used in the exceedingly high line of a kind of the whole network on public network intercom, and antenna covers China
Mobile communication, China Telecom, 2G, 3G, 4G frequency range of China Unicom and all frequency of GPS, BD, bluetooth, WIFI, the band of frequency
Width includes 800-2700M+1560M+1575M.Structure and sense of the present invention using No. three unipole antenna core pulling DC earthing short circuits
Answer what the principle of wideband designed, antenna oscillator is attached on FR4 epoxy glass fabrics using copper foil form.
First, the electric current of module enters oscillator A2 by mono- tunnels of common port E6 that the interface conductive pin of antenna enters in figure, shake
About 1/4 wavelength of the length of sub- A2, the place of top bending is the length for shortening antenna, there is a sense between oscillator A2 and oscillator B3
Capacitance is answered, shortens antenna oscillator and is coupled out broader frequency band, the another way of common port E6 passes through the direct front ends of ground terminal F7
Direct direct current to FR4 reverse side to earth mat above, above earth mat of the earth mat directly by the interface of antenna, make antenna more stabilization,
Bandwidth is more flat, and impedance comes out frequency range 1500-2170M closer to 50 ohm, by the first via with regard to resonance, and standing-wave ratio is less than 2.0,
Gain is more than 2dBi.
Second, the electric current of module enters oscillator B3 by mono- tunnels of common port E6 that the interface conductive pin of antenna enters in figure, shake
Similar 1/4 wavelength of length of sub- B3, the place of top bending is the length for shortening antenna, the volume-diminished of antenna is highly controlled
System is in below 35mm.There is inductance capacitance between oscillator B3 and induction end D5 and oscillator A2, antenna oscillator is shortened and is coupled out more
Wide frequency band, the another way of common port E6 by the direct direct current in the direct front ends of ground terminal F to FR4 reverse side to earth mat above, earth mat
Above earth mat directly by the interface of antenna, make antenna more stablize, bandwidth it is more flat, impedance passes through closer to 50 ohm
The first via comes out frequency range 824-960M with regard to resonance, and standing-wave ratio is less than 2.0, and gain is more than 2dBi.
Third, the electric current of module enters induction end D5 by mono- tunnels of common port E6 that the interface conductive pin of antenna enters in figure,
By similar 1/4 wavelength of length of induction end D5 connections oscillator C4, oscillator C, the place of afterbody bending is the length for shortening antenna
Degree, has inductance capacitance between oscillator C4 and oscillator B3, shortens antenna oscillator and be coupled out broader frequency band, common port E6's is another
All the way by the direct direct current in the direct front ends of ground terminal F to FR4 reverse side to earth mat above, earth mat directly passes through the ground of the interface of antenna
Online face, make antenna more stablize, bandwidth it is more flat, impedance comes out frequency range closer to 50 ohm, by the first via with regard to resonance
2170-2700M, standing-wave ratio are less than 2.0, and gain is more than 2dBi.
Obtained by comprehensive such scheme, the band section 824-960/1500-2170/2170-2700M of inventive antenna, meets us
Design requirement include China Mobile's communication, China Telecom, 2G, 3G, 4G frequency range of China Unicom and GPS, BD, bluetooth, WIFI
All frequencies, are that the bandwidth 3% of original unipole antenna is lifted to 15%.The efficiency of full frequency band is more more than 40%, the standing wave of antenna
Than less than 2.0 and in the case of meeting gain, by size Control in below 35*7.5mm, by invention antenna product use in public network
Above intercom, since the antenna is DC earthing, by the earth mat above public network intercom antenna can be made more to stablize, increased
Beneficial higher, standing-wave ratio is more flat, is thought of as the dipole asymmetric antenna of wideband.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
Understanding without departing from the principles and spirit of the present invention can carry out these embodiments a variety of changes, modification, replace
And modification, the scope of the present invention is defined by the appended.
